re: re: Southwest airline fatality, did her death save others?

Southwest has become a larger airline than they ever envisioned themselves being. This is all because of the industry fallout after 9/11 and subsequent mass consolidation, which allowed them to more than double their size in about 15 years. Now, they fly to too many places and have over 700 airplanes to look after. It's big burden. They still don't do any contract maintenance to my knowledge.

I'm ignorant here as I only glanced at a few of the headlines when this happened and haven't read more....but I thought the 1 fatality was a lady that was hit with damaged equipment? I thought the lady that got sucked into the window was pulled back to safety by other passengers, did the lady going into the window die?
The lady that got sucked out is the fatality.
Supposedly everything from her waist up was outside the plane for a few moments until pulled back in by passengers.

Considerably different situation. Decompression from 9 atmospheres to 1, roughly 135 psia (120 psi) to 15 psia (0 psi) in the diving chamber vs 1 atmosphere to 0.25 at 35,000 ft altitude, That's 15 psia (0psi) to 3.75 psia (-11.25 psi)in the plane.
My suspicion is that an injury as a result of the debris that broke the window rendered her unconscious which is why she was sucked into the window as the air was rushing out. Once the cabin equalized (assuming the hole was not permanently plugged, the suction would have ceased. The stuff you see on movies is mostly nonsense.

And keep in mind this plane was at 24,000 feet when it started falling apart.
And I imagine the o2 masks went with the roof. I guess the people in first class regained consciousness when the plane dropped low enough?

Not sure. I know they dropped altitude rapidly. I'm not sure I would have ever flown again had I been on that flight.

But to think about that poor lady and the experience she suffered, all you can hope and pray for it that she didn't endure any kind of pain and it happened so quickly that she didn't realize what was going on.
heard on the radio this morning that she died from result of impact
so it was likely very quick....probably didn't even know what hit her

I'm guilty of unbuckling my seat belt when the pilot gives permission to do so. But I now understand the importance of keeping it buckled and why it is more than just a suggestion.
They said she had her seat belt buckled.

Some guys climb Mt Everest without supplemental oxygen. You just can't stay at that altitude for long periods - days, not minutes. I doubt the Aloha Air passengers lost consciousness, although they might have wished they would have. That had to be a terrifying experience.
I'm sure the Aloha Air flight descended rapidly. I think I read that it was on the ground less than 20 minutes after the accident. The Southwest flight descended ~20,000 in ~5 minutes. No oxygen would have been needed at that altitude. I'm not positive, but I think I remember hearing/reading that a commercial airline cabin is pressurized to a similar atmosphere as ~8,000'. I know it's not sea level.

The military studied how much time pilots would be able to make useful decisions after losing pressurization at different altitudes. At 25,000 feet the average person would have 3-6 minutes, 22,000 5-10 minutes, this plane landed on the ground 13 minutes after losing the roof, the rate of decent was probably fast enough that no one actually lost consciousness.
Altitude (measured barometrically)
TUC Time of Useful Consciousness
FL150 (15,000 ft; 4,550 m) 30 minutes or more
FL180 (18,000 ft; 5,500 m) 20 to 30 minutes
FL220 (22,000 ft; 6,700 m) 5-10 minutes
FL250 (25,000 ft; 7,600 m) 3 to 6 minutes
FL280 (28,000 ft; 8,550 m) 2.5 to 3 minutes
FL300 (30,000 ft; 9,150 m) 1 to 3 minutes
FL350 (35,000 ft; 10,650 m) 30 secs to 1 minute
FL400 (40,000 ft; 12,200 m) 15 to 20 seconds
FL430 (43,000 ft; 13,100 m) 9 to 15 seconds
FL500 (50,000 ft; 15,250 m) 6 to 9 seconds

How unlucky was this poor woman?
1) She was on this flight
2) She was seated next to the debris impact point
3) The debris shattered a window, rather than just punching a hole in the fuselage
4) Her seat belt fails
5) She's petite enough to be partially sucked out of the window.

This is where I really struggle. She's petite, and the seat belt fails?
I know this is a freak one in a billion accident... but you have to wonder if we need to think about stronger seat belts and windows.

I'll be interested in more details about the alleged seat belt failure. Did the buckle fail? Did the belt itself fail? Anchoring hardware fail?
Surely there's some type of maintenance requirement. They've got to be inspected and/or replaced after some period of time, I would think.

That pretty much is a 100% fatal event. When this happens you are sucked out through a window in about half a second that you normally could not force yourself out of even if you tried very hard. So it is breaking shoulders, clavicles, arms and probably some ribs and maybe even her neck just doing that. Now the top half of her body is suddenly in 500 mph wind. The force on this of a body stuck there is almost impossible to imagine. The wind has enough force to tear exposed skin. Her arms would suddenly flail so hard the would be shattered in several places. It is almost certain her neck would have been broken. Eye lids could be torn and her jaw dislocated just form the force of the wind. Not to mention the air doing all that is about -30F degrees and can freeze her skin in seconds. I am sure that just to get her back in took a few people pulling on her like hell."

She likely had her sealt belt buckled, but it was also likely very loose. Even people who buckle on airplanes dont usually tighten the belt

One report today said her seat belt was fastened. (I think it was the second guy who is a medic and who with someone else gave her CPR all the way back to Philadelphia.)
